| 摘要 |
The present invention relates to an active magnetic field sensor, in particular a wheel bearing sensor unit, comprising at least one magnetic sensor element (10, 21, 36) for converting a temporally periodic magnetic field into a temporally periodic electric sensor signal at signal outputs (37, 31) and an electronic signal-evaluating circuit, the said magnetic field sensor being electrically fed by way of a sensor interface, wherein an active electric processing of periodic signals (38, 39) of the magnetic sensor element is performed in two or more separate signal channels of the evaluating circuit respectively associated with the sensor signals. The present invention further discloses a motor vehicle influencing device and a method preventing a vehicle from rolling on an inclined plane.
